Abstract
A finite strain numerical analysis is employed to investigate the void growth induced anisotropy and additional softening. In order to simulate the microscopic process, homogeneously and regularly distributed cylindrical voids are assumed and plane strain and generalized plane strain analyses are carried out. The material is assumed to satisfy the normality rule based on the von Mises yield condition and to obey the exponential type hardening law. The results include the changes of shape of voids and void fraction ratio and macroscopic stress-strain relations under radial loading paths with various ratios in the principal stress and strain space, and the subsequent yield condition in macroscopic stress (or strain) space after finitely strained states.
